Made under the hot sun and blue skies of California, 'Light and Space' art serves as an early model for some of the most radical and ground-breaking art forms of the last century: immateriality and the site-specific installation, as well as situationist and participatory art. The movement's fascination with colour, and its manipulation in space, serves as a very different kind of minimalism, a movement often thought of as simply the embodiment of austere, mathematical abstractions.
